Woah impressive that's a nice find. Was this at a store or did you get this online? Also on the topic of SEGA pickups I picked up these two games recently from my local game shop.
Also not shown was Virtua Racing which I also got.

It's meager, but I have most of the best games for the system, and that was my goal. The only others I really want that I'm missing are Rocket Knight Adventures 2, Beyond Oasis and Crusader of Centy, a Zelda clone (CoC is really expensive).
